Home represents a place of safety, belonging, and continuity. It forms the core of one's identity through the mosaic of smaller elements that make up one's sense of home, including culture, language, landscape, and smells. The loss of home through displacement can cause a profound sense of nostalgic disorientation that disturbs this substratum of identity. Nostalgia describes both the physical and psychological pain of being separated from this place of origin and the desire to return home.
